Description

Technical Field

[0001] This utility model relates to the field of internal mixer technology, specifically to a dust purification device for internal mixers. Background Technology

[0002] In the processing and production of materials such as rubber and plastics, the internal mixer is a key piece of equipment, widely used in processes such as material mixing and plasticizing. During operation, especially in the discharge stage, the internal mixer generates a large amount of dust. This dust mainly originates from friction, crushing, and volatilization of the materials during the mixing process.

[0003] If this dust is not dealt with promptly, it can cause many serious problems. From a production environment perspective, large amounts of dust will permeate the workshop, leading to a severe decline in air quality and a deteriorating working environment. This not only affects the operator's visibility and increases the difficulty of operation, but also poses a significant threat to the operator's health. Long-term exposure to high concentrations of dust can easily lead to occupational diseases such as respiratory and lung diseases.

[0004] From a production safety perspective, when dust mixes with air and reaches a certain concentration, it is highly likely to explode when it encounters a source of ignition, seriously threatening the safety of the production workshop and potentially causing serious consequences such as casualties, equipment damage, and production interruption.

[0005] From a product quality perspective, dust can adhere to the components of the internal mixer and the surface of the manufactured products, affecting their appearance and performance. For example, in the production of rubber products, dust may reduce the adhesive properties of the rubber and affect the physical and mechanical properties of the product. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a dust purification device for an internal mixer, mainly used to purify the dust generated during the discharge process of the internal mixer. The device mainly includes an internal mixer 1, a dust collection frame 2, and a dust collection module 3. The internal mixer 1 adopts existing technology, with a dust collection frame 2 installed at its discharge port, and a dust collection module 3 arranged beside the internal mixer 1. The dust collection frame 2 and the dust collection module 3 are respectively provided with several dust discharge ports and dust collection ports, with the dust discharge ports connected to the corresponding dust collection ports. The dust collection module 3 can create a negative pressure inside the dust collection frame 2 and filter the air carrying dust before discharging it.

[0025] The dust collection frame 2 includes a manifold box 21 and a side suction box 22 installed near the discharge port of the internal mixer 1. The upper surfaces of both the manifold box 21 and the side suction box 22 are connected to dust discharge connectors 23, and their lower surfaces are pre-drilled with dust collection holes 24. The manifold box 21, the side suction box 22, the dust discharge connectors 23, and the dust collection holes 24 are all interconnected. This structural design allows dust generated at the discharge port of the internal mixer 1 to enter the manifold box 21 and the side suction box 22 through the dust collection holes 24, and then be discharged through the dust discharge connectors 23.

[0026] The vacuum module 3 includes a fan 31 and a filter module 32. A manifold valve 33 is installed at the suction end of the fan 31. The manifold valve 33 has several air inlets and one air outlet. The air inlets are connected in series with the air outlets of the suction pipes 34, and the air outlet is connected in series with the suction end of the fan 31. When the fan 31 is working, it generates suction, which draws air from the multiple suction pipes 34 into the fan 31 through the manifold valve 33.

[0027] The suction end of the manifold valve 33 is connected to the suction pipe 34, and the suction end of the suction pipe 34 is connected to the exhaust connector 23. In this way, air inside the dust collection frame 2 can enter the manifold valve 33 through the exhaust connector 23 and the suction pipe 34, and then be drawn in by the exhaust fan 31.

[0028] The exhaust end of the exhaust fan 31 is connected to the air inlet end of the filter module 32. The exhaust end of the filter module 32 is connected to the exhaust pipe 35, and an exhaust cap 36 is installed on the exhaust end of the exhaust pipe 35. The filter module 32 includes an air inlet pipe, an air outlet pipe, and several filters. The air inlets of the filters are connected in series through the air inlet pipe, and the air outlets of the filters are connected in series through the air outlet pipe. The total air inlet end of the air inlet pipe is connected in series with the exhaust end of the exhaust fan 31, and the total air outlet end of the air outlet pipe is connected in series with the air inlet end of the exhaust pipe 35. The filters adopt existing technology and have built-in filter elements, which can filter air carrying dust.

[0029] Several vent holes are pre-drilled around the side of the exhaust cap 36 to allow the clean air filtered by the filter module 32 to be released into the environment. This design ensures that the filtered air is evenly distributed to the surrounding environment, preventing localized air accumulation.

[0030] During operation, the exhaust fan 31 starts and generates suction. A negative pressure is created inside the dust collection frame 2 through the manifold valve 33 and the suction pipe 34. When the internal mixer 1 discharges material, the generated dust is sucked away by the suction hole 24. After passing through the manifold box 21, the side suction box 22, and the dust discharge connector 23, the dust enters the suction pipe 34, and then into the manifold valve 33 and the exhaust fan 31. Subsequently, the dust-laden air enters several series-connected filters in the filter module 32. Under the action of the filters, the dust-laden air is filtered, the dust is retained in the filters, and the clean air is discharged through the exhaust pipe 35 and the exhaust cap 36. Operators only need to clean the filters and replace the filter elements periodically.
